Dual-Mapping Sparse Vector Coding for Phase Noise-Resilient Short-Packet Transmission
Yanfeng Zhang, Xi'an Fan, Xu Zhu +6
Sparse vector transmission (SVT) has emerged as a promising technique for ultra-reliable low-latency short-packet communications. However, existing SVT schemes typically assume neg…
Dual-Mapping Sparse Vector Transmission for Short Packet URLLC
Yanfeng Zhang, Xu Zhu, Jinkai Zheng +5
Sparse vector coding (SVC) is a promising short-packet transmission method for ultra reliable low latency communication (URLLC) in next generation communication systems. In this pa…
DFT-s-OFDM with Chirp Modulation
Yujie Liu, Yong Liang Guan, David González G. +1
In this paper, a new waveform called discrete Fourier transform spread orthogonal frequency division multiplexing with chirp modulation (DFT-s-OFDM-CM) is proposed for the next gen…
Basis Expansion Extrapolation based Long-Term Channel Prediction for Massive MIMO OTFS Systems
Yanfeng Zhang, Xu Zhu, Yujie Liu +3
Massive multi-input multi-output (MIMO) combined with orthogonal time frequency space (OTFS) modulation has emerged as a promising technique for high-mobility scenarios. However, i…
Chirped DFT-s-OFDM: A new single-carrier waveform with enhanced LMMSE noise suppression
Yujie Liu, Yong Liang Guan, David González G. +1
In this paper, a new single-carrier waveform, called chirped discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM), is proposed for the sixth ge…
